I think that she knows what her work entails but in an abstract way. She has never experienced it.

Given her character it should repulse her, on the other hand maybe the feeling of power inherent in tempting souls to hell might entice her (really unlikely I know)._________________So remember, when you're feeling very small and insecure;
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere up in space;
'Cause there's bugger all down here on Earth

First, peanut butter sandwiches, I love that. Just one more thing I love about this girl.

Second, she hasn't really liked anything about being a devil girl so far. She didn't get rid of the flutterguys. She read Glossy's books. She's utterly intimidated by Blue. I think she's going to hate working the booth. And when she does her first shift in the Pit she'll hate it. I just don't see her being the stabby-stabby kind.
